Chelle - I can't remember off the top of my head right now what I'm feeding them, but I know it's a chick starter and I don't think it's medicated. I'll check it out when I feed 'em tonight. Also, I chose the most "yellow" of the batch... there was only 12 available. I think that they were a bit on the smaller side of everyone. But there is one in this bunch who's pretty tall.
PPal - I know when they get older that the males will develop their little bitty comb.. and they have the funniest crow! I'm hoping to have at least 1 female.. is aggression an indicator at all? I have one white who's pretty snarky and the little black is very upfront about food-time.
